Terpstra" Cc: Palmer Dabbelt Subject: [PATCH] pcie-xilinx: OF-PCIe numbers legacy interrupts from 1 Date: Fri, 23 Jun 2017 14:57:20 -0700 Message-Id: <20170623215720.27057-1-palmer@dabbelt.com> X-Mailer: git-send-email 2.13.0 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org From: "Wesley W. Terpstra" Without this patch we can't use the 4th legacy PCIe interrupt. This is a workaround: there are only 4 legacy interrupts, but since they're numbered starting from 1 instead of 0 this just adds a 5th interrupt.
